LINOTYPE-MACHINE Specification of Letters Patent.

T 0 all whom it may concern-.-

. Be it known that I, Hnnvaron DREWELL, engineer, subject of the German Emperor, residing at Charlottenburg, Germany, have invented new and useful Improvements in Linotype-Machines, of which the following is a specification.

The present invention rel-ates to 'linotype machines, and an important object is to provide improved means for guiding the matrices in the same.

In linotype machines there is arranged a guide spring above the collecting star at the place where the matrices enter into the assembling block from the guide channels of the collecting device. The purpose of this spring is to prevent the matrices, which fall at a high speed from the magazine, from flying too far and then not arriving at all, or not in the correct position',in the assembling block. In the customary constructional forms this protecting spring is comparatively short and as a slightly curved shape. At its front end it has two shortteeth which'hold back the upper ears of the matrices. The gap between these teeth is for allowing the space bars to pass freely into the collector or assembling lock in case the spring should happen to be bent rather too far to the front. This known arrangement is not sufficient, at high working speeds of the type setting machine, for preventing the matrices falling into confusion, being thrown out, or becoming jammed. Devices are also known, the object of which is to guide the matrices in various different ways. The majority of these devices however, are neither intended nor are they suitable for rapid working, ut are intended solely to protect the matrices as much aspossible.

. In the ordinary operation of a linotype composing machine, when a composer operates the machine directly at the key-board, it is true that these defects are not so very noticeable. For the composer works comparatively slowly; also he supervises the assembling of the matrices and at any moment can interfere in order to remedy a disturbance. But as soon as the composing machine is operated automatically with the aid of a perforated register band, such disturbances occur very frequently. It then requires a comparatively long time in each case to remedy them.

Now an important object of the present a fork, the central portion of the invention is to provide means which remedy these defects. This is obtained on the one hand by a suitably shaped guide spring for the matrices, and on the other hand by providing a second spring in addition. This admits of the composing machine operating with great certainty even at the highest speeds.

In order that the invention may be clearly understood, reference is made to the accompanying drawing in which one embodiment is re resented by way of example diagrammatical-y,a11d' in which:

Figure 1 is a vertical transverse section through one part of the composing machine showing the two springs which form the subject-matter of is a front elevationshowing the lower portion of one of these two springs.

Referring to the drawing, 1 is the assembling block, and 2 the guide arranged in front 01 the latter. On the surface 3 of the latter there is a spring 9 on which the matrices slide down in order to arrive in the assembling block.

4 is a belt which runs over the wheel 5 and conveys the matrices to the guide 3; 6 are guide channels which receive the matrices from the magazine and bring them to the lace where they are assembled or to the belt 4. The collecting star 7 pushes the matrices which arrive below one after another into the assembling block 1. Above the inlet into the assembling block 1 is arranged the guide channel 8 through which the space bars pass into the assembling block. Now between the uids 3 and the lower opening of the channeTfS there was formerly a spring which had at its front end two lateral, short teeth. According to the present invention, instead of that s ring there are two springs 10 and 11. Of t ese, particularly the outside spring 11 which is directly in the position of the older spring, differs from the latter in its special, peculiar shape. Namely its front end is formed like sprin being removed up to. the dotted line 12 in Fig. 1. The lateral portions or prongs 13 and 14, which take the place of the short teeth used formerly, are first bent slantwise upward and turn vertically down again at the front. The incision between these prongs or teeth permit the s iace bars to pass freely between them when falling out of the chan- I :v ,4q.-" Q"? mai 3.
